What would you do if this evil lived inside you? Unseen. Unknown. An insidious disease so deadly and disastrous that it eradicated the majority of humanity in a matter of months? A pandemic with an unknown source and an unknown cure? A painless but assuredly fatal condition that robbed your body of the very bones that hold it all together? And what would you do if you and your child were somehow immune, secret survivors of this condition, watching on as a population desperate for a cure is tearing apart others in search of a solution? Would you speak up and help, or resign yourself to becoming the last human being on earth?
